Long iOS build times have historically been a significant productivity issue for mobile development teams, but Apple has addressed this with the introduction of Compilation Caching in Xcode 26, which reuses compiled outputs to reduce build times. Bitrise is the first CI/CD platform to implement this feature through its Bitrise Build Cache, offering the potential for faster builds by caching outputs like object files and module artifacts. This technology mirrors the caching methods long used in Gradle and Bazel, and Bitrise's infrastructure enhances its effectiveness, providing lightning-fast remote caching, detailed analytics, and a straightforward setup process. Testing has shown that using the Bitrise Build Cache can lead to significant reductions in build times, with reports of up to 55% faster builds and considerable savings in developer hours. While Xcode Compilation Caching is in its early stages, its performance is expected to improve over time, and it is already available for all Bitrise customers and trial users.
